The purpose of this study is to probe the peristaltic propulsion of a non-Newtonian fluid model with suspended gold nanoparticles. The base fluid is considered to simulate blood using the Carreau fluid model. We model a small annulus as a tube with a peristaltic wave containing a clot propagating towards the tube wall. An external variable magnetic field is also considered in the governing flow. An approximation for long wavelengths and small Reynolds numbers is employed to formulate the governing flow problem. The resulting nonlinear equations are solved using a perturbation scheme. Series solutions are obtained for the velocity profile, temperature profile, pressure rise and streamlines. The results indicate an enhancement in the temperature profile that can be utilized in eradicating tumour cells.
本研究旨在探讨含有悬浮金纳米粒子的非牛顿流体模型的蠕动推进。基液采用 Carreau 流体模型模拟血液。我们将一个小环建模为一个管，其中包含一个向管壁传播的血栓的蠕动波。在控制流动中还考虑了外部可变磁场。采用长波长和小雷诺数的近似方法来构建控制流动问题。使用摄动方案求解得到的非线性方程。获得了速度分布、温度分布、压力上升和流线的级数解。结果表明，温度分布得到了增强，可用于消除肿瘤细胞。
